Playing video's according schedule

hi all, I developed an application using jmf and swings which plays video clip's,scrolling text and pop-up window(panel) on a screen playing according to schedule ,

1.The problem is that we are getting blank screen between the video clips.

2. For ex.there are 5 playlist in schedular, but has to play according schedule but the playlist is not in the loop which should play for 24 hrs schedule.

we have tried on adjusting time concept but still the problem we are facing. could you please refer the code and let us know if any issues are there. Awaiting reply. . import javax.swing.*; import java.util.*; import java.awt.*; import java.awt.event.*; import java.lang.String; import java.io.IOException; import javax.media.*; import java.io.*; import java.lang.*;
